Abstract
Pistons for internal combustion engines often need additional cooling to attain better performance. One method of cooling involves adding oil to an oil gallery opposite a combustion zone. Adding a standpipe prevents a preestablished quantity of oil from exiting the oil gallery. Installing the standpipe intermediate a first baffle plate and a second baffle plate improves reliability of the piston and ease of manufacturing.
